class_docstr: A dict-like row of a tabular ``Dataset``.
  
  This implements the dictionary mapping interface, but provides more
  efficient access with less data copying than converting Arrow Tables
  or Pandas DataFrames into per-row dicts. This class must be subclassed,
  with subclasses implementing ``__getitem__``, ``__iter__``, and ``__len__``.
  
  Concrete subclasses include ``ray.data._internal.arrow_block.ArrowRow`` and
  ``ray.data._internal.pandas_block.PandasRow``.
